I have to admit that it all makes no sense to me anymore.
Once upon a time, we had world cups with only 16 national teams and only 1 host.
In a few years we will have a world cup with 48 national teams and 3 hosts, and I would not be surprised if in 2030 FIFA organizes a world cup with 64 national teams and 4 hosts.
Obviously, FIFA no longer cares about football but only about making money, so maybe in 20 or 30 years we won't have qualifications for the World Cup at all because all the national teams of the world will have the right to participate

I'm almost certain we'll have a world cup every 2 years soon.
All together this no longer makes sense.
Based on
Wikipedia, the current number of countries is 194 countries. It is inconceivable if finally, FIFA continues to increase the number of World Cup participants, meaning that there is no more pride for countries that qualify because their chances are even greater and competition is very likely to be less competitive.
It has been debated that FIFA is becoming an organization with a money orientation rather than developing football properly, unfortunately, there is not much that can be done and when they make many changes that focus on getting more money, many countries still desire to be the organizer of the world cup so they don't mind even though they are seen being used because being able to play in the World Cup until now is a pride for many national teams, especially when they understand that the opportunity to get it is difficult if they have to go through qualification, so the shortcut is to become a host by investing a lot of money.
Even if we have 194 counties in the world in some countries they don't have football at all or in some other countries football is not a priority and they pay more attention to other sports, I think increasing the number of teams can have bad effects because we can see more countries in the world cup we should not normally see them, more week team in world cup means lowering the quality.
